Particularly, our initial clinical experience has shown the DK-mini-culotte stenting has several advantages: (1) efficiently eliminating CUEB and preventing stent malapposition by IKBI;(2) technically easier to be performed, particularly for wiring/rewiring and for balloon passing during IKBI and FKBI; (3) technically safer to complete the procedure, especially for preventing the acute vessel occlusion or loss; (4) effectively preventing the deformation and collapse that occasionally happened when using the crush-based stenting; (5) mostly close to the general technique for treating BL regardless of size difference of branches and bifurcation angle; (6) potentially long-term benefits because of complete and even stent coverage in the treated segments particularly in the bifurcation arena and carina. However, there remains no strictly compared study to validate whether the above-mentioned technical superiorities can be translated into clinical benefits as using the DK-mini-culotte stenting for treatment of BL.
